Hyundai Sonata Santa Fe Tucson Kia Sorento Optima Sportage G4KE 2.4L L4 Engine 2011-2013

Description

Experience quiet valvetrain operation and restored cylinder balance with this Hyundai Tucson Kia Sportage G4KE Remanufactured Engine. Built for 2011 to 2013 crossovers, this 2.4L 4-Cylinder 16-Valve assembly features casting G4KE with Dual CVVT round oil hole ports. Rebuilders require strict pre-lubrication of all camshaft journals before initial crank to avoid catastrophic aluminum cam bore galling.

An open-deck die-cast aluminum block houses iron cylinder liners beneath head casting THETA-2 2.0/2.4. A balanced steel crankshaft spins on tri-metal bearings inside align-honed main saddles. Dual variable valve timing mechanisms control camshaft advance across 16 intake and exhaust valves. Dry long block weight equals 250 lbs. The shipping crate envelope dimensions measure 36in length by 36in width by 36in height. The factory oil pan holds 4.9 quarts of motor oil.

Key Features of Hyundai G4KE

Fleet service managers buy Hyundai G4KE remanufactured engine long blocks to fix crankshaft seizure and restore original fuel economy. This precision powertrain assembly provides OE fitment for sport utility vehicles requiring specific round oil hole cam phasers.

• Block cast G4KE undergoes precision CNC surface milling to ensure a flat deck finish.
• Cylinder head casting THETA-2 2.0/2.4 features round oil hole feeds for dual CVVT phasers.
• Diamond plateau cylinder honing provides optimal surface Ra finish for low-tension oil control rings.
• Micro-polished crankshaft journals maintain 0.0003in TIR runout to prevent connecting rod knock.
• Upgraded tri-metal rod and main bearings resist metal-to-metal contact during cold engine starts.
• Multi-layer steel head gaskets ensure tight combustion chamber seal under high operating temperatures.
• New torque-to-yield cylinder head bolts prevent head lift and maintain uniform clamp load.

Dyno Load Precision Machining Tolerances

Dyno load cell testing verifies 176 HP at 6,000 RPM and 168 ft-lbs of torque at 4,000 RPM. Crankshaft journal runout measures less than 0.0003in TIR while rod bearing oil clearances hold between 0.0012in and 0.0016in. Precision diamond plateau honing yields a 12 to 16 Ra cylinder wall finish. Hot oil pressure checks show 58 PSI at 3,000 RPM at a regulated 195°F coolant operating temperature. Cylinder compression gauges show 185 PSI across all 4 cylinders. Align-honed main bearing saddles maintain hydrodynamic oil film stability under high RPM load.

Vehicle Fitment Drivetrain Guide

This remanufactured long block fits 2011 to 2013 Hyundai Tucson built between production dates 1/11 to 8/13 and 2011 to 2013 Kia Sportage built between production dates 1/11 to 10/13. Vehicle applications require the 2.4L 2359cc engine code G4KE, head casting THETA-2 2.0/2.4, and dual CVVT with round oil holes. Suitable for FWD and AWD models with 6-Speed automatic transmissions. Does not fit 2.0L turbo engines, GDI direct injection platforms, or pre-2011 slotted oil hole heads.

Installation Protocol Service Requirements

Verify electronic throttle body harness connections and torque transmission bellhousing bolts to factory specs. Technicians must replace the vehicle oil cooler assembly and flush radiator tanks to eliminate debris left behind by past engine bearing failures. Do not operate this long block under forced induction or nitrous boost above factory atmospheric levels.

• Pre-lube the engine by priming the oil galleries with 5W-20 oil prior to starter motor activation.
• Drain the break-in motor oil and install a new oil filter at 500 miles to capture metal wear particles.
• Perform subsequent oil and filter changes every 3,000 miles to protect variable cam phaser solenoids.
